DREB2 — Cicer arietinum

Summary

LOC101507986, designated CaDREB2 (also known as DREB2A and DREB2B) on chickpea chromosome 2, encodes a DNA-binding transcription factor containing an AP2/ERF domain. The product is annotated with NAD ADP-ribosyltransferase, ubiquitin-protein transferase, and transcription coactivator activities. CaDREB2 is associated with the upregulation of chlorophyll breakdown, leaf senescence, and defense responses, as well as with stomatal complex development, trichome branching, photoperiodic flowering, and nitrogen fixation. The gene is linked to yield, plant height, leaf relative water content, photosynthetic rate, transpiration rate, and responses to water stress, osmotic stress, and UV-B light. It is also associated with root development traits, lateral root length, and root oxidative activity. Localization evidence places the product in the nucleus, cytoplasm, nucleolus, and RNA polymerase II core complex.
